Abstract
The utility model relates to a novel large shaft sleeve positioning structure comprising a pump shaft, a shaft sleeve, which is characterized in that an inner wall on the two ends of the shaft sleeve is relative to the pump shaft, a groove is arranged on the pump shaft on the relative side, a O-ring seal is arranged in the groove, a long key groove is arranged on the pump shaft surface on the relative other side. A key groove hole is arranged on the shaft sleeve corresponding to the long key groove, a key with screw thread through hole is disposed on a centre shaft in the key groove hole, an inner hex head screw is position in the screw thread through hole on the key, the inner top end of the inner hex head screw contacts the bottom of the long key groove, a ring is coated on the outer top surface of the inner hex head screw, two symmetrically distributed long key grooves are arranged on the pump shaft surface. The utility model has the advantages that the shaft sleeve and the shaft are reliably sealed, the axial displacement of the shaft sleeve and the circular rotation can be restrict.
Description
Technical field
The utility model relates to a kind of shaft sleeve positioning structure, particularly a kind of novel large shaft sleeve position structure.
Background technique
Present pump class axle sleeve is generally cylindric, locatees a side that is generally axle sleeve and be close to the shaft shoulder on axle, or withstand the another one part, and opposite side is locking nut locking.Shortcoming: one, sealing is unreliable between axle sleeve and the axle, only depends on the paper washer that adds between the surface of contact of axle sleeve and other part to seal, and area of contact is little, and sealing effect is just poor.Two, on the axle locking nut is arranged, on the axle screw thread must be arranged, the shaft portion of screw thread and fixed axle sleeve will have tool withdrawal groove, and the processing tool withdrawal groove is easy to generate wedge angle, influence axle intensity; Simultaneously, the shaft diameter of screw thread opposite side can only be little one grade, and for identical axial wood, this structure is low to the utilization ratio of material.Three, for big screw thread and locking nut, detecting needs very expensive detection equipment, and the yielding capacity of magna pump is seldom, expensive device vacancy rate height, and little producer does not generally dispose these expensive device, and this can influence a part quality.
Summary of the invention
The purpose of this utility model is to solve large shaft sleeve and existing the problems referred to above of pump shaft position structure in the prior art, and a kind of novel large shaft sleeve position structure is provided.The utility model designs a kind of novel large shaft sleeve position structure, comprise pump shaft, axle sleeve, it is characterized in that: the two ends inwall of axle sleeve is relative with pump shaft, circumference is fluted in the pump shaft upper edge of a relative side, O-ring seals is arranged in the groove, on the pump shaft face of relative opposite side, long keyway is arranged, with the corresponding axle sleeve of long keyway on corresponding dowel hole is arranged, the key that tapped through hole is arranged on the axis is arranged in dowel hole, in the tapped through hole on key socket head screw is arranged, the interior top of socket head screw and long keyway bottom offset, and are with an annulus on the outer end face of socket head screw.Two long keyway that are symmetrical distribution are arranged on the pump shaft face.The utility model has the advantages that axle sleeve and shaft sealing are reliable, the axial displacement of axle sleeve and circumference rotation can limit.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise pump shaft 1, axle sleeve 2 among the figure, it is characterized in that: the two ends inwall of axle sleeve 2 is relative with pump shaft 1, pump shaft 1 upper edge circumference fluted 3 in a relative side, O-ring seals 4 is arranged in the groove 3, on 1 of the pump shaft of relative opposite side, long keyway 5 is arranged, with long keyway 5 corresponding axle sleeves 2 on corresponding dowel hole 6 is arranged, the key 8 that tapped through hole 7 is arranged on the medial axis is arranged in dowel hole 6, in the tapped through hole 7 on key 8 socket head screw 9 is arranged, the interior top of socket head screw 9 and long keyway 5 bottoms offset, and are with an annulus 10 on the socket head screw 9 outer end faces.On 1 of the pump shaft two long keyway 5 that are symmetrical distribution are arranged.
By the circular hole on the annulus 10, tighten socket head screw 9, interior hexagonal spiral shell 9 screw tops are lived pump shaft 1, key 8 moves outward, key 8 holds out against annulus 10, and annulus 10 deforms, and embraces pump shaft 1, can not move, axle sleeve 2 is because the rotation of axial displacement and circumference can not be given birth to, the energy stable position in the location of key 8 on pump shaft 1, annulus 10 can not move owing to be out of shape, and also can stablize not come off.
Claims (2)
1, a kind of novel large shaft sleeve position structure, comprise pump shaft, axle sleeve, it is characterized in that: the two ends inwall of axle sleeve is relative with pump shaft, circumference is fluted in the pump shaft upper edge of a relative side, O-ring seals is arranged in the groove, on the pump shaft face of relative opposite side, long keyway is arranged, with the corresponding axle sleeve of long keyway on corresponding dowel hole is arranged, the key that tapped through hole is arranged on the axis is arranged in dowel hole, in the tapped through hole on key socket head screw is arranged, the interior top of socket head screw and long keyway bottom offset, and are with an annulus on the outer end face of socket head screw.
2, by the described a kind of novel large shaft sleeve position structure of claim 1, it is characterized in that: two long keyway that are symmetrical distribution are arranged on the pump shaft face.
